## Additional Libraries and Code used

GeoServer uses several additional libraries and pieces of code.  We are 
including the appropriate notices in this file.  We'd like to thank all
the creators of the libraries we rely on, GeoServer would certainly not
be possible without them.  There are also several LGPL libraries that do
not require us to cite them, but we'd like to thank GeoTools - 
https://geotools.org, JTS - https://locationtech.github.io/jts/
 WKB4J https://wkb4j.sourceforge.net, OpenPDF - https://github.com/LibrePDF/OpenPDF,
and J. David Eisenberg's PNG encoder https://www.catcode.com/pngencoder/

### Apache License

GeoServer uses a number of libraries licensed under the Apache License, 
Version 2.0.  These include Spring - https://www.springsource.org/,
a number of Apache commons libraries - https://jakarta.apache.org/commons/
whose jars we distribute and include in our source tree under lib/.  Also 
included as libraries are log4 https://logging.apache.org/log4j/docs/index.htmlj, 
batik https://xmlgraphics.apache.org/batik/, and xerces https://xerces.apache.org/xerces-j/.

Note there is some disagreement as to whether GPL and Apache 2.0 are compatible see 
https://www.apache.org/licenses/GPL-compatibility.html for more information.  We
hope that something will work out, as GeoServer would not be possible without
apache libraries.

    JAVA SERVICE LAUNCHER (JSL) is PUBLIC DOMAIN.

    This means the software is FREE. Free means you may use or reuse

    as the JSL parts of it are not covered by this copyright.

    You may distribute derived work in executable form and not include 
    the JSL source code if JSL constitues only a minor part of the 
    intellectual work (in other words, you can take the executable and

    may not charge in particular for or discriminate against the use of 
    the parts derived from JSL.
